The cahn-hilliard equation
網頁We examine a viscous Cahn–Hilliard phase-separation model with memory and where the chemical potential possesses a nonlocal fractional Laplacian operator. The existence of global weak solutions is proven using a Galerkin approximation scheme. A continuous dependence estimate provides uniqueness of the weak solutions and also … 網頁1984年3月1日 · This paper treats phase separation within the context of the phenomenological Cahn-Hilliard equation, ct = ∇ · [ M ( c )∇ ( ∂f / ∂c - K ∇ 2c )], where c is the concentration, M ( c) is the mobility, and f ( c) is homogeneou s free energy, which is assumed here to be a fourth degree polynomial. Natural boundary conditions are …

網頁Abstract We consider a time-fractional Cahn–Hilliard equation where the conventional first-order time derivative is replaced by a Caputo fractional derivative of order $\alpha \in (0,1)$. Based on an a priori bound of the exact solution, global existence of solutions is proved and detailed regularity results are included.
